MEANS FOR ATTACHING PLATES TO FABRICS.

Specification of Letters Patent.

, T 0 all 107mm it may concern:

Be it known that I, JOHN lYiLLann CLAIP, a citizen of the linited States, and a resident of Avon, in the county of Norfolk and (ourinonwealth of Massachusetts, have invented certain new and useful In' provemcnts in Means for Attaching vPlates to Fabrics, of which the following is a full, clear, and exact description.

While this invention relates to a new and corwenient means for attaching any kind of thin plates to fabrics. it is especially designed for securing sheets of glass, mica, celluloid or other transparent material, to umbrellasv curtains, capes etc. for the purpose of supplying an inexpensive window thereto.

Referring to the drawings forming part of this specification, Figure 1 is a View of an umbrellashowing my invention a iplied thereto. Fig. 2 is a. view nearly full size, showing the preferable shape of frame used for attaching transparent material to an umbiellaor the like. Fig. I) is a sectional enlarged view showing a plate in the process of being attached to a fabric. Fig. 4 is a'similar View but showing the plate fully attached. Fig. 5 is a view similar to the last but showing the fabric cut away from within the frame to form a window through the same. Fig. 6 is a sectional view shou ing preferable manner of inserting the plate in place.

As is easily demonstrated, a person who is trying to shelter himself beneath an umbrella froma driving storm, is liable at any moment to collide with some pedestrian, or, if endeavoriug to cross a street, with some cal or other vehicle. To remedy this de} feet, l have devised the inexpensive and easily applied window forming the subject matter of this application.

The shape ofwindow best adapted forumbrellas, both to enable the latter to be properly rolled up, and to cause the minimum of wrinkling therein when the unrbrella. is extended, is the acutely iriangular one shown in Figs. 1 and 2. window is desired than the single narrow frame 1 shown in Figs. 1 and 2, two thereof can be arranged side by side, as shown at 2 in Fig. 1. By having the separating space between them quite narrow, they become. practically a single window.

The frame 5, which is preferably acutely triangular in outline, is composed of sheet metal doubled upon itself transwa'sely. but with one part, as 7, wider than the other; this if a larger" proximately forty-five degrees therewit 1, and with the ilane of the frame. This frame having been aid upon a suitable sup ortingsurface, such as a table, wlth the tango 6' uppermost, the fabric 15 in which the Win dow is desired, is spread smoothly over the frame. and then the properly shaped plate'10 of celluloid or other material is ressed down upon the fabric between the anges of the three parts of the frame, as indicatedin Fig. 3. Said flanges are now hammered or other wise forced over and down toward the wider part of the frame, thereby pinching the folds of the fabric thus made, and the edges of the )late, tightly between the two parts or anges of the frame, as shown in Fig. 4. By means of a knife-point 0r fine scissors, the fabric extended between the three sides of the frame is cut away, and the window completed. As is clearly evident, it requires but a few seconds to form awindow in this manner, whether in an umbrella, a curtain, the cape of a water-proof to hang over the weare'rs face, and other fabric-screens. In the same manner, name plates, whether of metal or paper, and other plates and sheets can be easily attached to fabrics and the like.

A thou h I have described the two flanges 6 and 7 0 each member of the frame as being of unequal width, 1 do not restrict myself thereto, as the only necessary oint is that the flange 7 shall project fart ier horizontally than the flange 6 does before it has been inched down upon the plate 10 and the fa )ric-folds.

As shown in Fig. 2, the frame. 5 is preferably formed with curved, or semi-circular, ends; the radius of curvature at the base being longer than that at the a ex of the frame, in order to give the same t 1c triangular general shape above described. Not only is this forin of frame more inexpensively manufactured than one with three straight sides soldered together at the angles, but I find that the fabric does not wrinkle or pucker as it is liable to do when the frame is made with sharp corners. Less metal is required for the curved ends as compared with the angular ones, and consequently a slightly lighter frame is rodueed.

As previously describct the plates 10 are pressed directly down between the upstandmg flanges 6, so that they come between narrower part or flange .6 not being parallelf with the other, but rising at an angle of a the opposite upstanding flanges simnlteneously. I find it a better pian to enter the plate-edge at one side of :1 plate 10 before the 0 posite edge is put into engagement with 1ts flange 6. The advantage of this that the plate can be introduced with a snugger fit than in the other Way.

What I claim my invention and for which I desire Letters Patent, is as follows,

'15 and having a flange bent over inwardly from emeee the outer periphery of the said body; the edges of said" olete being clamped between said body em flange, and the edges of an invention, I have hereunto set my hand this 25 21st day of February, 1907.
